Nowadays Nanotechnology is covering a wide range of industrial products. For instance, nanotechnology aims at enhancing conventional textiles with greater functionality. It has added intelligence to them and created thus smart clothes. Such smart textiles can react to environmental conditions. They find uses in many applications ranging from military and security to personalised health care. Remarkable nano fibers are now being developed, capable of filtering out viruses, bacteria, and hazardous particles. Actually the garments made up of nano fibers are easily cleanable, prompt to absorb body odour and reduce its excretion, to regulate the body temperature and to perfume the skin.
